Nice happy song! You wait a while to bring up the Cubs or even baseball in general, so for the first minute I wondered if I was witness to some sort of surreal juxtaposition experiment.
I think if you polished up the vocal just a tad, maybe doubled it? it might work a treat.
I understand the love of a perennial lost cause - Padres and Mariners fan here. But this year could be it for the Cubbys!
cheers,
